1992 Buick ParkAve Magnavox Ignition Question

Hello all,
I just acquired a 1992 Buick Park Avenue (beautiful car, great conditon,
interior in amazing shape) with about 140K on it.
Original 3800 motor, trans and all.

Outside a couple blown fuses and brakes, this is a great car.
In the first week, however, a miss has developed.
Finally figured out which cylinder it was, and have determined the injector
to be good, the wires and plugs to be good, just no spark from the
coil/ignition module.
this thing, unlike the three other 3.8's I own, has the Magnavox
(pronounced 'maggots-in-a-box' to all us old electronics sales/repairmen)
ignition system instead of the three coil Delco system.
Only one of the six is not firing. I know nothing about this ignition
system. Is it more than likely just the coil, not the ignition module, or
both? Is it even possible to replace just the coil and not the module?
Any help is appreciated. I really want to do this as cheaply as possible.
I only gave $500 for the car, but couldn't pass this one up.
Thanks in advance for all your help (which you guys always are!)

You can replace the "coil pack module", p/n 12353801, for about $125. You
never mentioned which one of the six isn't firing. However, start by
checking the resistance of the secondary coils by sticking a meter between
plug wire terminals 3 and 6, then 5 and 2 and finally 1 and 4.
Cylinder number are left to right when looking at the front of the car:
Front bank: 1-3-5
Rear Bank: 2-4-6
...and the coil pack is like this:
3 6
5 2
1 4
Oh, and check the plug wires, you never mentioned if you checked that or
not.

I've got conflicting info Shep. I've got two seperate part numbers for the
coil pack unit and the control module. I can see the Magnovox type is a one
piece coil, not like the typical three coil set up. But anyway, ACDelco,
ALLData and Mitchell all show different parts available to be purchased
seperately. ACDelco has nice pictures too.
But, I'm not speaking from experience, just what I'm reading.

i believe what he's getting at is if there's a failure in just one
plug, & it's
the coil, then the resistance between those two
wires (which fire at the same
time btw - just another tidbit of info)
would be very high, if any conductivity
at all exists. in other
words, a broken connection. however, if you're showing
anywhere near
the same resistance between all three pairs, then i don't know
where
the problem is unless it's just somehow grounding out. if you've
got an
oscilloscope, you could check to see if the ignition pulse is
even making it to
the coil in the first place.
